Unknown, unrecognized useful ability before the present invention relates to, it can be by being at water under certain condition relevant with the pH level with the concentration of dissolved oxygen, water is exposed to the oxygenant that produces stabilization in the magnetic flux of certain variation, and thinks that the oxygenant of this stabilization is the stable form of hydrogen peroxide in water (or other liquid).Method of the present invention provides the accumulation of a kind of oxygenant in liquid to form and keep mode, and described oxygenant provides different deactivation and/or biological static and kill biomembranous effect.As noted earlier, only for purpose is discussed, the liquid that the back often will be handled is regarded water as, but the present invention is not limited to only treating water, but also can be used for handling other liquid.
Method of the present invention comprises the pulse that water is exposed to the ring magnetic flux, and wherein flux interaction forms stable oxygenant in water.The device that the ring flux field for example can be awarded by on May 16th, 2000 in people's such as Crewson the United States Patent (USP) 6063267 (also transferring transferee of the present invention) provides, at this by with reference to it is all incorporated.The magnetic flux that passes water that is produced by this device is the successive pulse form, or the cycle form of ring magnetic flux, wherein the vibration of the magnetic flux in ringing cycle is that primary frequency is higher relatively as the positive harmonic wave of 10kHz to 80kHz, and also repeat to the frequency between 100Hz, the preferred 50 to 60 hz with 1Hz ringing cycle itself.
In the device of United States Patent (USP) 6063267, the circuit that is used to produce the pulse of continuous ringing magnetic flux comprises the inductor arrangement of being made up of one or more electrically-conductive coils, and these electrically-conductive coils are around the pipeline of transport process water.This inductor arrangement is by linking to each other with the 60Hz power supply that voltage is about 5 to 50V (rms) with the switch of a little electric capacity parallel connection.In the initial stage of each power-up period, the about four/one-period of switch closure forms electric current like this in inductor arrangement.Then when switch throws open, supply with the current interruptions of inductor arrangement, thereby make inductor arrangement and the effect of electric capacity polyphone, so form the serial resonant circuit with voltage source, the decaying pulse that ringing current on inductor arrangement, occurs, this ringing current with impose on by telefault around the corresponding ring magnetic flux of ducted water relevant.
The present invention is not necessarily limited to adopt the device of United States Patent (USP) 6063267 to produce required pulse of continuous ringing magnetic flux or cycle.Other device also can be used for this purpose.Generally speaking, think ring magnetic flux of the present invention each pulse or the primary frequency in ringing cycle should be 10kHz to 80kHz, and pulse or cycle should be with 1.0Hz to 100Hz, preferably the frequency with 50 to 60 hz repeat.Should there be a residence time each ringing pulse or cycle back, and this residence time equals 4% to 20% of each repeat cycle at least.
As another device that produces the ring magnetic flux, by linking to each other with power supply with switch that inductor arrangement is connected with power output terminal, the output primary frequency of described power supply is about 10kHz to 80kHz around the inductor arrangement of aqueduct.Related with switch then controller with 1.0Hz to the speed of 100Hz, preferred 50 to 60 hz open, Closing Switch so that ringing current cycle or pulse are provided in inductor arrangement, it is corresponding with ring magnetic flux cycle or pulsion phase in the water.
The ring magnetic flux of inductor arrangement is used for producing oxygenant at water; So current must be close to the ring magnetic flux, are adorning the pipeline or the miscellaneous equipment of water and must made by plastics or other electrically nonconducting material, so that allow magnetic flux by in the entry of going forward side by side, so most of magnetic flux directly passes water.
According to the present invention, find when pH be exposed to by 7 to 10, preferred 8 to 9 the water that contains a large amount of dissolved oxygens above having during the ring magnetic flux of discussion feature, produced anti-(bearing) peroxygen oxidising agent with sterilization ability.Even the microorganism that exists in the water is the microorganism that can form or form microbial film or bio film precursor, this oxygenant also can perhaps bring bigger Asia to cause death and injure the significant kill activity of these microorganisms.
Favourable application of the present invention result from Fig. 1 by way of example the air conditioner cooling tower shown in the mode the field border in.Shown in cooling tower be " crossing current " design, but the present invention also can be used for the cooling tower of other type.With reference to Fig. 1, the figure shows a part that is installed in usually than the air-conditioning system in edifice such as house, apartment, office building, hospital and the factory.Shown in this part system comprise cooling tower, condenser 12, pumps 14 with 10 overall indications.Cooling tower 10 utilizes given water body work, and some water are maintained in top distribution or the spray chamber 13, and most of water is retained in the main storage tank 14.Solenoid electric valve 18 by being subjected to the water yield control in the main storage tank 14 add make up water by makeup water line 16 as required, thereby the water yield that will comprise water body maintains in the given minimum and maximum limit.Water flows to the main storage tank 14 through a plurality of evaporation packing materials or honeycomb plates 20 etc. from upper chamber 13, and meanwhile fan 22 is blown over these honeycomb plates 20 with ambient air, is beneficial to evaporation of water.Arrow 24 expression environment air admission cooling towers 10, arrow 26 expression air leave cooling tower 10.
By the water cooling of packing material or honeycomb plates 20 evaporations the unevaporated water that stays, the temperature that arrives and stay the water in the main storage tank 14 like this is relatively low.
Cold water in the storage tank 14 device 12 that is condensed is used to cool off by entering the mouth and 26 flows into condensers 12, and flows out the heat exchange medium of condensers by outlet 28.Pump 14 is extracted cold water out in storage tank 14, and offers condenser 12 by cold line 30, the upper chamber 13 that makes it get back to cooling tower by hot water pipe line 32 from condenser 12 then under warm state.So pipeline 30 and 32, pump 14, condenser 12, upper chamber 13 and packing material or honeycomb plates 20 have constituted a part of water body from the 14 beginning recirculation of main storage tank and get back to the stream of this main storage tank.Because this recycled water is when the sheet material 20 and the ambient air intimate contact, therefore in the main storage tank and contain a large amount of dissolved oxygens in the water by pipeline 30 and 32, the water of for example per 1,000,000 weight parts contains the oxygen of 3 to 15 weight parts approximately, and the water of preferred per 1,000,000 weight parts contains the oxygen of 5 weight parts approximately.
What conform to the present invention is, in the cooling tower of Fig. 1 is arranged, the pulse of ring magnetic flux be imposed on from main storage tank 14 beginning recirculation and gets back to wherein that part of water.In order to realize this purpose, shown in the solid line among Fig. 1, comprise ring magnetic flux generating unit 36 in the cooling water pipeline 30, this device 36 is preferably for example shown in the United States Patent (USP) 6063267 and the device of describing.As to installing 36 replacements that are arranged in the cooling water pipeline 30, selectively this device is arranged in, in the hot water pipe line 32 shown in 36 place's dotted lines.On in two selectable locations shown in Figure 1 any one, the water of process device 36 or ' 36 all contains a large amount of dissolved oxygens, this device operation like this, and hydrogen peroxide or other oxygenant of generation stable form in water are so consume most of dissolved oxygen.In addition, as noted earlier, importantly through install 36 or the pH level of the water handled of ' 36 a little more than neutral pH value 7, acceptable pH level is the value in pH7 arrives the pH10 scope, its preferable range is that pH8 is to pH9.Fortunately, realized as shown device 36 or ' 36, it is found that, the pulse of ring magnetic flux is imposed on treating water always can produce this pH level inherently in cooling tower 10 water body, and it is maintained on neutral above the accepted pH level, like this, (even if the words that have) seldom require specially water to be carried out extra process for the pH level of regulating water.
According to mentioned, think that the stable form of hydrogen peroxide or complex compound are exactly the oxygenant that method of the present invention produces.Particularly, think that the hydrogen peroxide that produces is according to pH or H 2O 2Non-ionic form, or HO 2Ionic species, other complex compound complexing that exists in this ion and another ion or the water then, form the stable form or the complex compound of hydrogen peroxide, the decomposition of these stable forms or complex compound lags behind, perhaps just decomposes when the chemical ingredients of it and microorganism is reacted.More accurate, after having produced hydrogen peroxide by the ring magnetic flux pulse that applies feedwater, the equilibrium equation of related compound, ion and complex compound is:
(Eq.1)
HO then 2Combine with have positive change, negative variation or neutral complexing ion or other complex compound that changes that exist in the water, form stable comple, H 2O 2And the balance equation between these stable comples becomes:
Can replenish by the poising action of equation 2 by the used up hydrogen peroxide of oxidizing bacteria.It has the effect that equation 2 is driven left, just obtains some hydrogen peroxide again from the storage attitude of stable comple thus.Although pure hydrogen peroxide has lost its anti-microbial effectiveness rapidly because of decomposition, the ring magnetic flux can form stable hydrogen peroxide complex thing because of water is exposed in water under this ring magnetic flux.Another kind of oxygenant is an ozone, its sterilizing activity and hydrogen peroxide similar; And the stable form of ozone (can combine separately or with the stable form of hydrogen peroxide) can be the oxygenant that forms by wide model method of the present invention.
Before being exposed to ring magnetic field, water carried out the aeration processing, when the water that thereby the water that makes dissolved oxygen concentration in the water reach relative 1,000,000 weight parts contains the oxygen of three (3) to 15 (15) weight parts, preferably reach 1,000,000 weight parts contained the oxygen of 5 weight parts approximately, the formation of oxygenant will be enhanced.Aeration can be realized by the known mechanical device of any amount, comprise jet flow, injection and packing material or honeycomb plates, in order to allow bigger fluid surface be exposed to atmosphere.
Although dissimilar bacteriums and other microorganism can be in by the water of ring magnetic flux processing of the present invention inactivation, the Gram negative bacteria seems and affects adversely than Gram positive bacteria is easier.Fig. 2 to 4 expression ring magnetic flux is to the beyond thought sterilising effect of enterobacter cloacae, and the existence of this bacterium represents that water is polluted by fecal matter.Fig. 2 represents that colony-forming unit (CFU/ml) inactivation in time of every milliliter of enterobacter cloacae changes.Thereby among the present invention be exposed to for a long time the ring magnetic flux accumulated the water sample of oxygenant (■-) at 24 hours with the interior remarkable minimizing that shows colony-forming unit concentration.But, form another kind of water sample (●-) if in these water, add Sulfothiorine, bacterium has not just been had effect.Any oxygenant that exists in Sulfothiorine and the treating water reacts, thereby allows these oxygenants decomposition or invalid.These two samples (■-and-●-) experimental results show that following principle: stable oxygenant is the stable oxygenant that forms in water by the processing of ring magnetic flux pulse.By comparison, only use chlorine treated water sample (σ-) can not provide and the identical enterobacter cloacae colony-forming unit deactivation of handling with the ring magnetic flux of water degree.
The unexpected discovery of people has dependency with the kill activity of ring magnetic flux treated water to pH.When water be weakly alkaline, when pH is about 8 to 9, sterilising effect is the strongest.Among Fig. 3 processing water sample under the weakly alkaline pH condition and near the processing water sample the neutral pH are compared.Colony-forming unit pH8.45 place enterobacter cloacae subtracts at most (v-).Under need not the situation of treatment process of the present invention, bacterium be normally flourishing in 8.45 the water at pH.Along with pH drops to neutrality, the kill activity for the treatment of water also reduces.Be about 7.2 at pH (*-) time, the quantity of colony-forming unit only descends in time slightly.
Fig. 4 represents the influence of Sulfothiorine to the oxygenant in the treating water once more.The water of handling according to the present invention (v-) has been realized the remarkable minimizing of enterobacter cloacae colony-forming unit.But along with the adding (■-) of Sulfothiorine, the oxygenant inactivation is so the colony forming single-digit order of bacterium maintenance is constant.Obviously, oxygenant forms in water after water is exposed to the pulse of ring magnetic flux.
The purpose that the present invention has been claimed above having realized.Rich oxygen containing stable oxygenant, for example hydrogen peroxide of stabilization have been produced with ring magnetic flux burst process water for the water treatment and the purification of simple cost usefulness.The stabilization oxygenant that produces by method of the present invention has significantly reduced the colony-forming unit of bacterium, and provides and avoid, reduce and/or eliminate biomembranous effective means.
Though specifically described the present invention in conjunction with certain preferred embodiment, obviously, according to aforementioned description, carrying out multiple replacement, improvement and variation is conspicuous for those of ordinary skills.Therefore can be contemplated that claims have contained all these replacements, improvement and variation, they all drop in essential scope of the present invention and the spirit.
